Interrupting a loop in a GUI [message #38483]

I wrote a GUI for displaying a camera picture that looks like this:
Thereï¿½s a display for the pic, some buttons to set display parameters
and a button to START the camera.
My problem is, when I press the START button, the event starts an
infinite loop in my _eventcb program that is aquiring pictures from
the camera forever...

The question now is:
How can I interupt a loop from another button, i.e. how can I create
the STOP button on my GUI Surface. Or how can I change parameters
during the camera loop is running.

Usually IDL waits until the process in the _eventcb is finished before
it executes another thing from the GUI Surface.
I guess there is a very simple answer, but I don't know it... :-)
